Description
The Bel VRBC-10F2Ax modules are a series of non-isolated dc/dc converters that deliver up to 10 A of output
current with full load efficiency of 94% at 3.3 V output. These modules provide precisely regulated voltage
programmable via external resistor from 0.75 V to 3.63 V over a wide range of input voltage (2.4 V-5.5 V).
These modules have a sequencing feature that enables designers to implement various types of output voltage
sequencing when powering multiple voltages on a board. The open-frame construction and small footprint
enable designers to develop cost and space-efficient solutions. Standard features include remote On/Off,
remote sense, over current protection, short current protection, wide input, and programmable output voltage.

Notes: 1. These modules use a buck topology, so the output voltages must be 0.5 V less than the input voltage.
2. Add “G” to the end of the Model Number to indicate Tray Packaging.

1. VRBC-10F2Ax series of modules include a sequencing feature that enables users to implement
various types of output voltage sequencing in their applications. This is accomplished via an additional
sequencing pin. When the sequencing feature is not used, tie the SEQ pin to Vin.
